Referring to the drawings in detail, a motor dr ven snow plow in accordance with this invention comprises a chassis consisting of a Iront bar 1, a pair of side bars 2, 3, and end bar 4, transverse brace bars 5, 6, spaced longitudinally extending supporting members 8, 9, 10 and 11, which are arranged between the brace bars 5 and 6, and longitudinally extending supporting members '12, 13, arranged between the rear bar 4 and transverse brace bar 5. The bars and supports which constitute the chassis are secured together by holdfast devices 14. The front bar 1 is of greater length than the rear bar 4. The side bars 2, 3 incline in opposite directions with respect to each other and the .inclination is outwardly from the rear end to the forward end of the side bars 2, 3. The front bar 1 is secured to the side bars, rearwardly with respect to the forward ends of said side bars and the portions of the side bars 2, 3 which project forwardly from the front bar 1, are indicated at 15. The bars 1', 1, 5 and 6 of the chassis are inthe form of 1- bars and the side bars 2, 3 are inthe formof channel bars.

The bar 1 has secured to its upper face a pair of spacedbearings 16, 17. The bar 6 has secured to its upper face a pair of spaced bearings 18, 19 aligning respectively with the bearings 16, 17. I Secured to the supporting members 8, 9 is an internal combustion motor 20 for driving the shaft 21 which is journaled in the bearings 16, 18-and projects forwardly with respect to the front bar 1 of the chassis. Secured to the supporting member 10, His an internal combustion motor 22 for driving a shaft 23, which is journaled in the bearings 17, 19 and extends forwardly from the front bar 1 of the chassis. Secured to the spaced supports 28 which extend from bar 6 to the inverted yoke shapedmember 55, is an internal combustion motor 23 for propelling the plow. The motor 23 operates a rear wardly directed drive shaft 24, which drives a differential 25, for driving the rear wheels 27 carried by the rear axle 26. Brace members 28 extend forwardly from the rear wheels27, and are connected with the transverse brace bar 6. Connected to the supports 12, 13 is a transverse suspension member 26 which is connected to the rear spring 26 and the latter is connected at its ends with the axle.

The plow includes a front truck which is pivotally connected with the transverse bar v ed against the top and bottom of each knuckle 33 are respectively coupling members 38, 39 and through which the pivot bolts 32 e1;- tend. The coupling members 38, 39 have their rear ends suspending below and pivot ally connected with the bar 6, as at 40, by hanger pieces 41 and bolts 42. The rear ends of the coupling members are torsionally twisted, see Figure 3. Connected to the ends of the bar 6 are forwardly extending, oppositely disposed and inwardly inclined brace members 43, which are loosely connected to theaXle 29, as at 44. See Figures 3 and The coupling members pivotally connect the front truck to the chassis.

For the purpose of elevating and lowering i the forward end of the chassis, a pair of elevating screwsiare provided and which are in dicated at 54:, see Figure 5. The elevating screws 54% are provided with hand wheels 521/ at their upper ends. Said screws or have thread-ed engagement, as at 5 1- with an in verted yoke shape member 55, which extends transversely with respect to the chassis and has its arms 56, fixedly secured as at 57 to the side bars of the chassis. The yoke e tends a substantial distance above the chassis and the screws 54; bear against and engage in socket forming members 55 secured upon the top of the axle 29 of the front truck; By adjusting the screws 54 the front of the chassis can be elevated and lowered relative to the front truck due'to the front truck being pivotally connected to the chassis.

Arrangedforwardly of the chassis, as well. as extending above and depending below the same is a housing :58 provided with a pair of spaced fan chambers 59, (it) and in which operate respectively iction fans 61, 62." The housing is formed with au' open front and the fan chambers are arranged at the rear thereof. The intake for each chamber is indicated at 63. The side bars 2, 3 extendinto the housing 58 and secured to the sides there of. The forwardly projecting portions of the side-bars 2,3 of the chassis, and which are indicated at 15, see Figure 1 are fixedly secured to the housing for the purpose of suspending the latter forwardly of the chassis.

r The shafts 21, 23 extend into the housing, and

carry cutters 64:, 65 respectively which are arranged within the housing at the open front thereof and in advance and spaced from the fans 61, 62 respectively. The cutters opcrate forwardly of the intakes 63 for the fan chambers.

Leading from the fan chamber 59 and extending at an inward inclination is an outlet 66 for the chamber 59 and extending from the chamber 60 and at an inward inclination is an outlet 67 for such chamber. The outlets 66, 62" extend toward each other. The top of the housing 58 is provided witha tubular extension 68 which encloses theoutlet 66, 6'? and said extension 68 at its upper end" is flanged as at 69. The outlet 66, 67 are also flanged at their upper ends, as at 70. Ad: justably mounted on the flange 7O isa delivery member 71 provided with a pair of spouts 72, 3 which register respectively with the outlet 66, The delivery member 71 is of curved contour so that when adjusted in one position it will delivcrthe snow to the right or when adjusted in another position it will deliver snow to the left. The delivery member 71 is flanged at its lower end as at 74. A sectional annulus 7570f channel-shape in vertical section overlaps the flanges and 74: and seats on the flange 69. Thesections of the annulus are detachably connected togethat their ends, as at '75, see Figure 1; The holdfast devices between the sections offthe annulus can be adjusted so that the delivery 1 ember can be shifted from the full line position as shown in Figure 4L- to the dotted line position shown in such figure or to any other desired position. Bracing means, as indicated at 76, 77 and 78 are provided for the delivery member and an annulus 75. The flanges 69, i0 and 74: are of circular contour.

The fansprovide snow removing or delivery means of the suction type and operate synchronously with the cutters 6st, 65, but these latter attack the snow in advance of the action thereon by the fans, under such conditions the snow removing or delivery' operation is greatly facilitated. To prevent the bottom of the housing 58 engaging with an uneven road surface, pieces of ice,.or other obstacles, it is mounted on runners 79 having upturned front and rear ends. Braking mechanisms for the rear wheels 27 are indicated at 27. An operating means common to said mechanism is indicated at 27 and is supported from the bars 9, 10.

When the machine is propelled, through the operation of the motor 23, the'motors 20 and 21 are also set into operation,'causing thereby a synchronous operation of the cutters and the suction devices or fans, and as the machine moves in a direct line against the snow, the cutters will cut the same and the snow will be taken up by the suction fans and delivered to the outlet 66, 67 from there into the delivery member 'Zl and the snow will be discharged to the'right or left of the line of travel of the plow.

It is thou ht theman advanta es lof a motor driven snow plow, in accordance withv this invention, can be readily understood, and although the preferred embodiment of the invention is as illustrated and described, yet it is to be understood that changes in the details of construction can he had which Will fall Within the scope of the invention claimed.

What We claim is:

A snow plow comprising a motor driven carriage, a vertical housing secured against the forward end of the carriage and having an open front, a pair of fan chambers Within the housing and each having its forward Wall open to provide an intake therefor, a fan Within each of said chambers, a snow cutter arranged forwardly of each fan chamber and at the open front of said housing, a vertical extension projecting from the upper Walls of said fan chambers, a curved discharge pipe sWivelled on the upper end of said extension, and an inclined outlet pipe leading from each fan chamber, said outlet pipes converging and terminating at the upper end of said extension for delivering snow directly and independently from each fan chamber to the discharge pipe.

In testimony whereof, We aflix our signatures hereto.
